Specification of letters Patent. Patented A11g", 19,1913, Application filed May 23, 191.?v Serial NO. 699,167.

To (ZZZ zMom it may concern Be it known that I, Lr'inmin RASCH'EN, a citizen of-the United States, residing at Alameda, inthe' county of Alameda and State of California, have invented new and useful Improvements in TypeJVr-iting Machines, of which the following is a specification. v

The object of the present invention is to provide a typewrit-ing machine which will permit of the operator writing continuously from one line to thevnext without having to impart to the carriage any motion other than that accompanying the ordinary printing with the type, thereby reducing the cost of manufacture, increasing the speed attainable on the machine, and materially reducing the noise.

' In the accompanying drawings, Figure 1 is a plan view of the machine, certain well known parts being omitted; Fig. 2 is a rear view thereof; Fig; 3 is a transverse section.

Referring to the drawing, 1 indicates the bottom or frame of the machine, to which are adjustably secured, as shown at 2, channel-shaped supports 3 for shafts 4 offront wheels 6, and similar supports 7 f9 wQ'i shafts 8 of rear wheels 9. The w l eels 6, as also the wheels 9, are suitably spaced from each other to permit of conveniently supporting thereon a cylindrical paper carrier 1U.

11 indicates key levers, of a well known type, and drawn upwardly by springs 5, to which levers are hooked, the lower ends of links 13, the upper endsof which are hooked to type-bars 14 carrying type 15 and pivoted upon standards 16 on a circular support 17, so that the ty e 15 of all of said ty e-bars, when actuate by the keylevers, escend at the same point on the upper surface of the paper carrier 10, being uided in their descent by the vertical gui es 18, erected upon a plate 19 secured upon an arch 21 su orted upon the frame of the machine.

The inkingribbon 22 'is in. the form of a circular disk, and is secured to a disk 23, a central shaft 24 of which is rotatably'supported in said arch. To said shaft is secured ,a pulley 26, around which travels a band 27 traveling also around a pulley 28 upon a vertical shaft 29 carrying a worm.

the same shaft 4 is mounted a gear wheel 42 controlled by dogs 38 and adapted to be intermittently rotated by a pawl 34 secured to a spring plate 36, depressed, each time a key lever is actuated, by a universal bar 37 extending longitudinally of the machine and pivoted at its ends, as shown at 39, and

adapted to be depressed by any one of the key levers 11. A spring 43 maintains said pawl 1n engagementjwith said gear whe l By this construction, with each-depression" of a key lever 15,, the gear wheel 32 is r0- tated through a small are, thus correspondingly rotating the wheel 6 on the same shaft and correspondingly rotating the cylindrical carrier so as to present a fresh surface of the paper for an impression by one of the type 15. The paper, shown at 41, is folded around the cylinder in a helical form. If it is desired that there should be a blank margin on the right hand side of the paper, said right llZlIlClID'iIY/glllul portian is folded under the main body of the paper, 1

when placing the paper around themylinder. It is retained on the cylinder by any desired means, a simple contrivance for this purpose being rubber bands, shown at 44, around the cylinder and paper, one around the u per port ipn athereof and the other around the lower portion.

Two supports 7 for the rear wheels 9 are arranged parallel with each other but at any desired obliquity to the frame of the typewriter, and, by reason of this obliquity and the corresponding obliquity at whidh the wheels 9 engage the cylinder, saidcylinder will be caused to have a longitudinal as well as a rotary motion. The degree of obliquity at which the supports 7 and wheels 9 are set will determine the extent, of said longitudinal movement with each revolution of the cylinder and therefore also the line spacing The pitch of the helix in" which the paper is wound around the cyl-.

inder should correspond with the line spacing, so that, when the paperis unwound, the lines will be arallelwith the top and bottom of thepaper. By the intermittent rotation of the shaft l which carries the gear wheel 32 there will be also produced an intermittent rotation of the vertical shaft 29 and therefore also of the circular ribbon 22, so that fresh inking surface is continually supplied.

It is evident that, by this construction, the cost of manufacture and the noise, during operation of the 'machine are greatly @educedjthat produced in the ordinary machine by the return of the carriage to its initial position being entirely eliminated. On account of this return being no longer necessary the machine can be operated at much higher speed than prior forms of typewriting machines.

I claim 1. In combination with type bars, a cylindrical paper carrier, means for supporting the same contacting with said paper carrier at its cylindrical surface, means for operating said type-bars, and means for imparting a helical motion to said paper carrier with each such operation.

2. In a typewriting machine, the combination of a cylindrical paper carrier, wheels Copies of this patent may be obtained for upon which said carrier" is rotatably supported, type bars, means for operating said type-bars, and means operated with each operation of the type bars for rotating one of said wheels to rotate the carrier, two such wheels on o posite sides of the carrier being arrange obliquely to the axis of the carrier whereby longitudinal movement is imparted thereto.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
